C TODO
C * Clean up variable names, and try to decrease the number of distinct
C registers used.
C * Cleanup feed-in code to not require zeroing several registers.
C * Make sure we don't depend on uninitialized predicate registers.
C * We currently cross-jump very aggressively, at the expense of a few cycles
C per operation. Consider changing that.
C * Could perhaps save a few cycles by using 1 c/l carry propagation in
C wind-down code.
C * Ultimately rewrite. The problem with this code is that it first uses a
C loaded u value in one xma pair, then leaves it live over several unrelated
C xma pairs, before it uses it again. It should actually be quite possible
C to just swap some aligned xma pairs around. But we should then schedule
C u loads further from the first use.
